what kind of torque and power is it putting down, and where in the rpms? Jw if its gonna be like the yammy quick revver or the honda smooth power?

 

If they do run them, then they go with 4+1 rims to keep it narrow. What is your width in front in rear? I've raced many races and 46" is the most common width.

 

Look the stock z400 front wheels = 3.875" + 1.625" off-set so you won't gain much with 4 to 1's but I do run them. The width at the front is 47.5 and the rear is 47 even, this allows the rear to break loose when I need it to and gives more positive responce from the steering. I ran Powerline this past weekend and have run Sparta, and Loretta Lynns along with most of the Mid- South series plus some at Casey and the Saluki 100, the only people you see at 46" are running stock suspension the Z400 is at 45.9 and the yfz is 46.1.

 

Down here most run a +1 set-up. My R sits at 48' in the front and slightly narrower in the rear. Its wider than most but I have no problem in the trails. And when theres a wide open prarie I can take those turns harder for the pass.
